[Insight-users] Build with shared libs fails in VNL on Darwin

[Gavin Baker]

Hello,

I did a test build of ITK from CVS (fresh checkout today) on Darwin
(10.3.7), and got a failure compiling in VNL:

I suspected a problem with building with BUILD_SHARED_LIBS enabled, so
I turned this off and tried again, and it worked.  It would appear
some CMake/libtool voodoo is involved here.  Would it help to send the
generated Makefile?

Thanks -
